Making the case for the #CorsiRosenthalBox with studies.

A simple thread.
"no U.S. Energy Star certified air cleaners have CADR values (for either tobacco smoke, dust, or pollen) matching the CADR value for the CR Box even on low speed "

On cost? 1/10th.

1019 to 1444 m3/hr CADR.

(600 to 850 ft3/min)

Published here:
tandfonline.com/doi/full/10.10… ImageImage
An incredibly thorough study published in February 2023, with all of its authors from @NIOSH.

With universal masking in a 3-ply cotton mask, exposure to the relevant aerosol size is reduced by 88 to 94%, with the #CorsiRosenthalBox.

73% w/ CRBox alone.

sciencedirect.com/science/articl… ImageImage
Very good thread on this study here:

Essentially the same NIOSH team investigated HEPA efficacy.

65% reduction with HEPA alone.

So, at a much cheaper price, the #CorsiRosenthalBox gets better results.

cdc.gov/mmwr/volumes/7…
But can HEPAs remove SARS-COV-2 from the air? Yes.

(Would #CorsiRosenthalBox do the same? Yes - faster and cheaper.

Has it been studied specifically for this? No. HEPAs barely have.

Do the same laws of physics apply? Yes.)

journals.asm.org/doi/full/10.11… Image
But can HEPAs really remove SARS-COV-2 from the air?

Yes - in a UK hospital, HEPAs were off. Cov1d was in the air. Turned on. No more CoV1d.

1000 m3/hour CADR.

Remember the first study?

1019 to 1444 m3/ hour for the CR box.

@MarinaC_Dyb and her fellow authors found a massive reduction in aerosols in OCCUPIED classrooms using the #CorsiRosenthalBox. Also found that ALL of the air went in.

No wonder they have rolled them out to 400 locations.

Study is linked here:

Oh for Pete's sake. @elonmusk has just killed another thread.

Let me add these manually.
"Also found that ALL of the air went in" - quoting above to go into a little more detail:

This answers, in a study, the concern that it just moves the air around. That it won't go into the filter.

It does, and this had to be pointed out.
The CDC, of which NIOSH is part of, has officially recommended 5 ACH, minimum, and that DIY Air Cleaners are effective at reducing the risk of transmission of Cov1d.

The #CorsiRosenthalBox is
specifically mentioned as part of that solution.

cdc.gov/coronavirus/20… ImageImageImage
@3M has studied it in their formal lab - and is officially on board:

news.3m.com/2022-02-24-3M-…
The famous UL, Inc testing the safety of the #CorsiRosenthalBox, to make sure it won't catch on fire.

It won't - even if the filters are loaded up.

(The link that is out on Twitter appears to be dead.)

ul.org/library/2988
"Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?"

Yes.

pubs.acs.org/doi/10.1021/ac… Image
Some have expressed surprise that this was found.

Dr. Corsi explains:

And the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRi
A thesis - a study, that found 7 PFAs, and exposure to for both dog and human. (@ShellyMBoulder collaborated).
elischolar.library.yale.edu/ysphtdl/2161/ Image
How do we know that dogs are affected? Because it is dogs that get experimented on.

And not to get too personal, but my dog has stage 4 chronic kidney disease. CKD can be caused by PFAs.

Did I do that? Or at least not prevent it? A lot of

wunc.org/health/2021-05… Image
years with no air filtration.

But hey - she is 15 years old, and it could be just old age.

In any event, I don't want to go into any more detail, but now I know better.

But besides PFAs, dogs can catch Cov1d.

As can cats.

In fact, from the study, we should see our cat as part of our family regarding virus transmission.

Can a cat or dog wear a mask?

Yes, with training.

But what if you could reduce their risk of catching Cov1d without all that? Image
And the risk to the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRosenthalBox as the centerpiece of your family pandemic prevention protocol.

And it worked.

Thank you @BarryHunt008 for flagging this.

@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.

Lol.

They are just apparent supplement grifters.

I noticed they were using @NukitToBeSure's excellent torches as their example picture.

Strange to be so selective of an example picture for someone purporting to be an independent news source on health.

Hmm. I helped defend Nukit against charges of Image
racism by a very nasty couple who it turned out just do not like UVC, personally. I wonder....

Yep, ThailandMedicalX has blocked me.

But, it's weird for a purported news source to block someone like me @gorskon
@doritmi @19joho.

And them blocking me, is probably because Image

You've heard of "The Three Problem." - great book, and excellent Netflix series.

If you want to be avoid catching Covid, you probably have "The Empty Room" situation in the back of your mind.

How long after a room had people in it, can you safely demask?

Thread.

Measles was thought to be airborne after a child caught measles an hour after the infected child left the same office.

.

Interestingly, you can see the reluctance in blue below to call measles airborne. Much like the WHO with @mvankerkhove researchgate.net/publication/19…In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The...
which spent millions to rebrand SARS2 as "through the air" rather than airborne.

It is an inconvenient truth that then leads us to the study showing an #EmptyRoom SARS2 infection at 1 hour and 43 minutes, and FOUR HOURS and FORTY-FIVE MINUTES.

In this study, it comes with Experimental evidence suggests that SARS-CoV-2 remains viable within aerosols with a half-life of approximately 1-3 hours, though changes in aerosol microenvironment may shorten viability to minutes. However, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing of nasopharyngeal samples obtained from patients on an outbreak unit suggested in-room transmission of the delta variant, AY3 lineage, of SARS-CoV-2 to two patients admitted 1 hour, 43 minutes and 4 hours, 45 minutes after discharge of an asymptomatic infected patient. These findings suggest...

Mum's the word - if @SecKennedy is Mum.

You see, I have been a VERY FOCAL CDC critic. But you can't criticize without listening.

And I have been noticing that that the CDC has been very, very quiet.

NPR noticed as well. Image
This is crazy. Image
Yes, the @CDCgov has been deathly quiet.

90 times last year, versus 4 this year.

This is not MAHA.

This is MASA - Make America Silent Again.

And as one of the CDC's most focal critics? We NEED them to be sharing Public Health information. Image

I have a new thing to say to why I mask.

Ronald Reagan, Michael J Fox, Robin Williams, Lou Gehrig, Bruce Willis.

Alzheimer's, Parkinsons, Lew Body Dementia, ALS, CJD

All of them are dying or are dead from - the common cold.

You see,
One of the main viruses that results in the cold is a virus called OC43.

And it turns out that it's neuroinvasive - and is strongly associated with all of those diseases.

Even though it's just a cold in the beginning. So, those are 5 really bad diseases that I am protecting
myself from.

Kind of like HIV is often just like a cold or a mild case of flu in the beginning.

So, yeah, I mask so I don't catch a cold.

Or Covid - which is also neuroinvasive, and let me tell you all about the horrible things it does to your body much quicker....

Safer showering and swimming with great breathability!

Others have used a snorkel w/ N95s - but those then collapse around the snorkel, and breathability is more restricted. This new approach is w/ an internal BRACE!

I took a shower with this, and it worked perfectly. Build 🧵 Image
This is a great technique, but I was looking for something with more breathability.

Image
This is the internal brace, and how the magic happens.

My subconscious must have picked this up from surgical mask braces that go under surgical masks.

So, here's the build. Image

Got bored. Let's just check out Google Scholar and E Coli. Oh my. Oh my, that's not good.

Yes, yet another episode of "that's airborne, TOO?!!!!!"

THREAD
Pigs:
"Airborne E. coli were isolated from indoor air,....and downwind air samples (10, 50, 100, 200 and 400 m away) for five swine houses" (1)

Cows:
"E. coli was isolated in both inside and outside air, even in samples taken 150 m from the farm." (2)

READY FOR THE FUN ONES?
Restaurants:
"E coli was identified as the most prevalent illness-causing bacteria in Zone A-derived aerosols (721 CFU)"
(3)
Hospital:
"The results also showed that airborne bacterial pathogens were present in all the sampled hospital wards." (4)

Ready for another fun one?
